Problems solved by technology

[0004] The problems of the above types of nozzles are: (1) when the material enters the nozzle cavity, the pressure resistance will easily cause the mechanical vibration of the nozzle cavity, and the oil and gas cannot be fully mixed; (2) most of the existing nozzles are easy to crush the catalyst, resulting in oil Decrease in product quality, pollute the air; (3) Easy to coke, etc.

Abstract

The invention relates to a heavy oil catalysis atomizing nozzle, which comprises a first mixing chamber, a second mixing chamber, a nozzle chamber and a nozzle, the first mixing chamber and the second mixing chamber are fixed in the nozzle chamber, the first mixing chamber is arranged at an inlet end of the nozzle chamber, and the nozzle is arranged at an outlet end of the nozzle chamber; the heavy oil catalysis atomizing nozzle also comprises an atomization structure which is fixedly arranged in the nozzle chamber; the atomization structure comprises a support member and an atomization body, and the support member and the atomization body are fixed together; and the shape of the atomization body can be spherical shape, semispherical shape, progressively arc, elliptical shape or paraboloid. According to the invention, oil and gas are fully mixed, by means of the atomization body, oil and gas can be fully atomized, the taper-shaped controllable solid mist field can be formed, and the heavy oil catalysis atomizing nozzle has the advantages of simple structure, convenient usage, good operation elasticity and high reliability.

Description

technical field [0001] The invention relates to the field of nozzles, in particular to an indispensable high-efficiency heavy oil catalytic atomization nozzle in the production process of catalyst spray drying and catalyst molding for petrochemical industry. Background technique [0002] At present, the feed atomization nozzle is a key technology in the catalytic cracking process. In the heavy oil catalytic cracking process, the performance of the feed atomization nozzle plays an important role in the cracking reaction and product distribution; especially when the heavy oil is used as the raw material, this effect is particularly prominent. The well-atomized feed and high-temperature regenerated catalyst contact for a short time to carry out a violent catalytic cracking reaction, which can increase the yield of light oil, reduce the yield of coke, improve product distribution and prevent excessive cracking, and eliminate coking in the riser reactor phenomenon, bringing cons...
